The ON operation signals of the switches 65 and 66 are input to a control device 70 as control means provided in the casing 17, and the control device 70 recognizes the input ON operation signal as a reverse rotation command signal and controls the motor 18. Control is performed so as to rotate in the opposite direction to the previous rotation direction.

Here, the number of rotations of the rotating shaft 19 required to move the operating member 63 between the position where the switch 65 is turned on and the position where the switch 66 is turned on is determined by the transmission belt 2 and the moving body 44. The first and second driving pulleys 22, 23 and 24,
The number of rotations required for winding the reel 25 is the same as the number of rotations required. Therefore, from the above, when the moving body 44 travels to the end point position on the pillow base 7 side and the end point position on the base member 8 side, it reverses and moves in the opposite direction to the moving direction up to that point. It is.

In this case, when the moving body 44 has traveled to the end point position near the pillow base 7 and the end point position near the base member 8, the fixing of the mounting plate 64 is performed so that the switches 65 and 66 are turned on by the operating member 63. The position needs to be adjusted. For this adjustment, the hook hole 67 and the through hole 68 are made horizontally long so that the mounting plate 64 can be moved in the horizontal direction by an amount corresponding to the length of the hook hole 67 and the through hole 68.

A groove 72a is formed at the tip of the adjusting screw 72, and a holding piece 64d formed on the mounting plate 64 is formed in the groove 72a.
Are fitted. Therefore, when the adjusting screw 72 is rotated forward and backward, the adjusting screw 72 advances and retreats with respect to the nut 73,
The mounting plate 64 is moved in the left-right direction by the reciprocating movement.

As will be understood from the above description, the fixing position of the mounting plate 64 is determined when the movable body 44 reaches the end point position on the pillow base 7 side and the end point position on the base member 8 side. Must be adjusted so that the switches 65 and 66 are turned on. In order to adjust the position, the guide rail 1 and the pillow base 7 each have a mark 74 for indicating the end point position as shown in FIG.
a and 74b are attached.

The position adjustment of the mounting plate 64 using the marks 74a and 74b is performed as follows. That is, first, the moving body 44 is moved to the end point position on the pillow base 7 side or the end point position on the base member 8 side, and the predetermined position of the moving body 44, for example, the moving direction end of the moving body 44 is marked 74a or 74.
Stop at the position that matches b. Next, in a state where the mounting screw 69 is loosened, the adjusting screw 72 is advanced and retracted to mount the mounting plate 6.
4 is moved left and right. When the moving body 44 is stopped at the end position on the pillow base 7 side, the switch 65 is moved to a position where it is turned on by the pressing portion 63c of the operating member 63, and stopped at the end position on the base member 8 side. In this case, the switch 66 is pressed by the pressing portion 63 of the operating member 63.
c is moved to the position where it is turned on. Thereafter, the mounting plate 64 is fixed to the casing 17 by tightening the mounting screw 69, and the lock nut 75 screwed to the adjusting screw 72 is tightened so that the adjusting screw 72 is not loosened. Since the distance between the switches 65 and 66 is set in advance to a distance corresponding to the distance that the moving body 44 moves between both end point positions, one switch is turned on by the operating member 63 at one end point position of the moving body 44. If operated, the position of the mounting plate 64 has been adjusted, and the positions of the switches 65 and 66 need not be adjusted again.

A slide member 90 housed slidably in the longitudinal direction of the guide rail 1 in a box-shaped guide portion 89 integrally formed on the lower side, and a seat portion 89 a and a slide member 90 formed on the guide portion 89. The slide member 90 disposed between
Is pressed by the protrusion 90a of the slide member 90 when the slide member 90 slides in the direction opposite to the arrow D when the slide member 90 slides in the direction opposite to the arrow D. The switch 92 is turned on via a leaf spring 92a, and one end is connected to the slide member 90 and the other end is a part of the guide rail on the pillow base 7 side of the flexible part 6 in this embodiment. It is composed of a wire 94 as a bending detection member made of one metal wire fixed to a holding plate 82 with a screw 93. Here, the connection configuration of the wire 94 to the slide member 90 is as shown in FIG.
4 is bent into an oval loop portion 94b, and a screw 95 passed through the loop portion 94b is screwed to the slide member 90.

A portion of the wire 94 facing the flexible portion 6 is formed in a coil spring portion 94a as a bendable portion that bends with the bending of the flexible portion 6, and the elasticity of the coil spring portion 94a. The wire 94 is prevented from being permanently deformed by the flexibility of the wire 94. When the guide rail 1 is extended, the wire 94 is pulled in a direction opposite to the arrow D as shown by a solid line in FIG.
Is moved in the same direction against the elastic force of the compression coil spring 91, and the switch 92 is turned on. Conversely, when the guide rail 1 is bent by the flexible portion 6, the coil spring portion 94a bends and the wire 94 is bent as shown by a two-dot chain line in FIG.
In order to move the whole in the direction of arrow D, the slide member 90
Moves in the direction of arrow D to turn off the switch 92. When the switch 92 is off, the control device 70 determines that the guide rail 1 is bent, and prevents the motor 18 and the heater wire 80 from being energized.

A power switch 96 is mounted on the rear surface of the casing 17 as shown in FIG. 1, and a power cord 97 and a remote control box 98 connected to the control device 70 are connected from the rear surface of the casing 17. Code 99 is derived. As shown in FIGS. 1 to 3 and 21, a cover 100 covering the casing 17, the first and second drive rollers 22 to 25, the tension mechanism 35, and the like is provided on the casing 17 with screws 101 (FIG. 18). , See FIG. 20).

Here, the controller 70 includes a microcomputer (not shown). The controller 70 energizes the motor 18 when the massage operation is selected by operating the remote control box 98, and energizes the heater wire 80 when the warming operation is selected. Then, when the warming operation is started, the timer function of the microcomputer or the timer operation of a separately provided timer is started, and even after a lapse of a predetermined time, for example, 8 hours from the start of the warming operation, the warming operation is not stopped. If not, the heater wire 80 is turned off. In this warming-up operation, the control device 70 controls the power supply through the heater wire 80 based on a detection signal of a temperature sensor (not shown) provided at a predetermined portion of the flat heater 76 to control the flat heater 76 to a predetermined temperature. Maintain temperature.

Further, when the operation of stopping the massage operation is performed, the control device 70 keeps the motor 18 energized until the switch 66 for detecting that the moving body 44 has reached the end point position on the base member 8 is turned on. When the switch 66 is detected to be turned on, the motor 18 is turned off to stop the massage operation.

As shown in FIG. 4 and FIG.
A pair of prism-shaped cushion members 102 as a holding member are fixed to the outer half of the main plate portion 1b. The thickness of the cushion member 102 is set to be considerably thicker than that of the flat heater 76, so that the pair of cushion members 102 is configured to be recessed, and when the user lays upward on the flat heater 76. The body is supported from both sides by the cushion member 102 and is held so as not to roll out.

The main body 103 of the massage apparatus is constituted as described above, and the main body 103 is a bag-shaped cloth inner body 1.
04 and the exterior body 105. Among them, the inner body 104 includes a cushion material 106 such as urethane foam except for a portion that covers an area where the massage rollers 42 and 43 move, and the outer body 105 includes a cushion material 107 such as cotton except for the lower half. Is included.

The exterior body 105 has two bands 108 and 109 shown in FIG. 24 attached thereto by a magic tape (trade name) 110, and the flexible portion 6 of the guide rail 1 is bent to massage the device. 24 is folded in two as shown in FIG. 24, the tips of the two bands 108 and 109 are connected by a magic tape 111 so that the massage device can be held in a folded state.

In order to receive a massage by the massage device constructed as described above, the guide rail 1 and thus the massage device are extended as shown in FIG.
After the power switch 96 is turned on, the head is placed on the pillow base 7 and the body is laid on the flat heater 76. At this time, the flat heater 76 is bent by receiving the weight of the user, but the flat heater 76 is sandwiched by the hollow portion 1g of the guide rail 1 and the holding plate 82 together with the support plate 77 on both left and right sides. You can receive enough weight. The flat heater 76 is provided on the support plate 7.
Since it is sandwiched between the pair of sandwiching pieces 7h in the pillow base 7 together with 7, it does not bend downward due to the weight of the shoulder portion.

After lying on the flat heater 76, the remote control box 98 is operated to start the massage operation. Then, the motor 18 is started, whereby the transmission belt 2 is taken up by the first driving rollers 22 and 23 (rewinded from the second driving rollers 24 and 25) or the second driving roller The moving body 44 reciprocates by being taken up by the rollers 24 and 25 (rewinded from the first driving rollers 22 and 23). The reciprocating movement of the moving body 44 causes the massage rollers 42, 4 to move.
3 moves while rotating against the back and feet via the inner body 104 and the outer body 105, thereby receiving a massage action.

Incidentally, in order to obtain good massage action from the massage rollers 42 and 43, the part to be massaged must be appropriately pressed against the massage rollers 42 and 43. In this case, when receiving a massage on the back, the back may be pressed moderately against the massage rollers 42, 43 due to the weight of the body, but since the feet are lightweight, the massage rollers 42, 4
3 will be insufficient. However, in the present embodiment, since the two outer massage rollers 42 that hit the foot are hardened, a sufficient massage effect can be obtained even if the pressing force is insufficient. Since the massage roller 42 on the inner side of the back, particularly near both sides of the spine, is softened, the back does not feel rough while receiving a sufficient massage effect by a moderate pressing force.

On the other hand, especially when the temperature is low such as in winter,
When the warming operation is started simultaneously with the start of the massage operation, the heater wire 80 generates heat and warms the body. At this time,
The heater wire 80 is controlled by the control device 70 to maintain a constant temperature to warm the body to an appropriate temperature. However, since the heater wire 80 is not disposed in an area within a predetermined distance from the pillow base 7, the heater wire 80 It is possible to prevent the occurrence of such a problem that the part is heated. The flat heater 7
6, the portion corresponding to the flexible portion 6 of the guide rail 1 has a low calorific value because the heater wire 80 is straight, but this portion is particularly problematic because it is a portion of the body where the buttocks hit. There is no.

Now, massage rollers 42, 4 for a desired time
When the operation for stopping the massage operation is performed after the movement of the motor 3, the control device 70 turns off the motor 18 when the moving body 44 reaches the end point position on the base member 8 side. If it is desired to sleep with the massage device as it is, the heater wire 80 is kept energized during a low temperature period such as winter. When the user wakes up, an operation for stopping the warming-up operation is performed, and the heater wire 80 is cut off. At this time, if the operation for stopping the warming-up operation is forgotten, the heater wire 80 is maintained in the energized state as it is, but the control device 70 switches the heater wire 80 for a predetermined time, for example, 8 hours, from the start of the warming-up operation. Automatically cuts off power and prevents wasteful power consumption.

As described above, according to the present embodiment, the base 10
Has a frame structure composed of a pair of guide rails 1, a pillow base 7 and a base member 8 arranged on both sides in the longitudinal direction, so that the guide rail, the pillow base, the driving device, As a whole, it is lightweight and convenient to carry as compared with a conventional configuration in which a moving body or the like is attached.

Since the pair of guide rails 1 and the pillow base 7 are connected by sliding engagement between the engaging recesses 1e, 1f and the engaging portions 7c, 7d, the assembling work is simplified. In addition, by suspending the transmission belt 2 over the guide pulley 12 attached to the pillow base 7, the pillow base 7 can be prevented from coming off from the guide rail 1, so that no special means for stopping the pillow base is required. I'm done.

Since the flat heater 76 is arranged between the pair of guide rails 1 and the body is laid on the flat heater 76, the massage is performed by the massage rollers 42 and 43 while warming the body and improving blood circulation. Therefore, a good massage effect can be obtained.

The flat heater 76 is connected to the cushion 7.
8 and the body is softly received by the cushion body 78, so that it is comfortable to sleep. Further, since the heater wire 80 of the flat heater 76 is arranged in a meandering shape, the heater wire 8
0 can be increased, and the calorific value of the flat heater 76 can be equalized in each part. In addition, since the upper surface of the flat heater 76 is covered by the cover member 79, the hollow shaft 45 bends under the weight of the user, so that the massage roller 4 is bent.
Even if the members 2 and 43 rotate while contacting the cover member 79, the breakage of the heater wire 80 can be prevented.

In addition, since the covering member 79 is made of felt having excellent wear resistance, the massage roller 4
It is durable even when rubbed by the wires 2 and 43, and can protect the heater wire 80 for a long time. Further, since the felt is excellent in heat conductivity and heat retention, the heat of the heater wire 80 is evenly transmitted to the entire covering member 79, and the flat heater 76 is heated.
Is more effective for uniform heat generation of each part.

In this case, since the flat heater 76 is unitized in a mat shape by sandwiching the heater wire 80 between the cushion body 78 and the cover member 79 by bonding or the like, the heater wire 80 may be displaced and moved. In addition, assembly to the base 10 can be easily performed. In this case, since the left and right sides of the flat heater 76 are mounted on the hollow portion 1g of the guide rail 1 together with the support plate 77, the holding plate 82 is applied from above and the screw 81 is tightened and fixed. Work can be done easily.

Since the guide rail 1 is hollow, the portion supporting the flat heater 76 has a high heat insulating property, so that the heat of the flat heater 76 can be prevented from traveling to the outside through the guide rail 1 as much as possible. . Moreover, since a plurality of ribs 1a are provided in the hollow interior of the guide rail 1, the strength is higher than that of a solid one using the same amount of material.

Further, the support plate 77 disposed below the flat heater 76 is hard and has a certain degree of rigidity, so that it supports the body well and helps maintain a good sleeping posture. For this reason, there is no possibility that the spine may be in an unusual posture, such as bending, and even if the massage device is placed on the floor without noticing that the small object is placed on the floor, the flat heater 76 is not It can relieve pain that is locally convex and hits the back.

As described above, since the patient is excellent in sleeping comfort and the body can be warmed by the flat heater 76, it is possible to sleep immediately after the massage. in this case,
When the end operation of the massage driving is performed, one moving body 44
Automatically moves to the end point position on the driving device 16 side and stops, so that the moving body 44 does not interfere. Even if the user forgets to stop the warming-up operation when he wakes up, the heater wire 80 is automatically cut off after eight hours from the energization of the heater wire 80, so that useless use of electric power can be prevented. In particular, in the case of sleeping overnight with the massage device instead of the bed, considering that the sleeping time is approximately 8 hours, the heater wire 80 is not automatically cut off during sleep, which is convenient.

When not in use, the massage device is folded by the flexible portion 6 of the guide rail 1 to fold the massage device in two.
At this time, even if the heater wire 80 is energized, the switch 92 is turned on in response to the bending of the flexible portion 6 and the heater wire 80 is cut off based on this, so that the heater wire 80 remains energized. In addition, it is possible to prevent a problem in which the massage device is folded in two and heat is trapped inside and the temperature rises to a high temperature. In this case, since the heater wire 80 is not disposed in a meandering shape at the portion corresponding to the flexible portion 6 but is linearly disposed, when the flexible wire 6 is bent, the heater wire 80 is not kinked and durable. The nature increases.

The heater wire 80 is connected to a lead wire 83, and the connector 8 provided on the lead wire 83 is connected to the heater wire 80.
5, the heater wire 80 can be easily connected to the power supply unit. In addition, the connecting portion between the heater wire 80 and the lead wire 83 has a waterproof connection structure by resin molding, and the connector 85 of the lead wire 83 is connected to the casing 1.
7 is connected to the connector 87 housed in the case 86, even if water is zeroed in the flat heater 76, the connection between the heater wire 80 and the lead wire 83 and the connector 85,
Inconveniences such as the wettability of the connection portion 87 and the deterioration of the insulating property can be prevented as much as possible.
